On the classical route from Riva del Garda to Passo Tremalzo (by bike, not by shuttle) you come about Passo Rocchetta (Moser Tremalzo 4). This place, in the middle of nowhere is sometimes quite crowded. It marks the end of the long uphill from Pregasina. From here it goes up and down to Passo Nota where the final ascent to Passo Tremalzo begins.
